Indeed. There is no need to scrap things, but if the design as it stands, and the intended means of creating objects for use in containers, is going to result in an unworkable network, then we have to re-evaluate how the container constructs are created, and that then has possible consequences for how we would get from an incoming packet to the proper container. I'm not trying to stop the "support train" here, but at the same time, if the train is headed for a bridge that's out.... --=20 Doug Ledford GPG KeyID: 0E572FDD --=-c7OMWg5gF1v5UBMrYl2S Content-Type: application/pgp-signature; name="signature.asc" Content-Description: This is a digitally signed message part Content-Transfer-Encoding: 7bit -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAABCAAGBQJVZ1zwAAoJELgmozMOVy/dSSYQAJqif1VrR0/mhmQgRqJHh8Ze xQ2Ewm+84ajmpBO960/PrzMzyMUdiJUgYtABXg8Vsnx6Xr1T0ZHOldmNVpHEumYv 9ktDuUVP6VatSPTSpuNMx1ibDqRmBN3lcUbJEV6brHW2qQ2QxiIrxqiAXzaEmaKX 2UtBhwwJkgcfrTRZKjnDpMaRpvWsbGaO4ilYe4WBjAxRaOEaxQKTHVMXM3ATlqwE QYUBxSSJ1+hjNogVFnPWll43jxMSvoCkk+UgwpqouiT5jGTS/q6d9Ebt1yD1Xbck 7rVUZKn/msvwQiZ1SjXFJPuzx2+rE9FYvyhrlSewALIplqsh5GVllGh4hWj0szk3 haqyrwUzj2kDt8HdKMyxMYHOcpt7Ns/7GHfSwt5Ms5/CA23k2LQaBDmH+6r+EbQx INIUrLYLKQFUeaFLH8jo5qskAnSaDCigGute9dbt7acVDxpajvaB1hwuiy0r4HRx D+NBme3yxnYMBNH0CYUHZuPdlnr+q4FRhbxtteXDolppx9iE5dwMUalvuSwOGZAL yPkGt5sTJ9hr9BaNLse4h+oicEM030ONZMudB1NTRjaLmYdllqf/G4zZF5c+ZIxw cnCYveU6wPlSQbbTGt9v9HE6RyAo+1VCVVchlll/mFOYTJYc/D8K+7lCQg9Fk/+B 0gCknS5Voc7OUBizxLje =HOXL -----END PGP SIGNATURE----- --=-c7OMWg5gF1v5UBMrYl2S-- -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
